"It's peace of mind. It's just such a good feeling."

WATCHMAN may be a life-changing alternative to the lifelong use of warfarin. In a one-time procedure, WATCHMAN effectively reduces the risk of stroke in people with atrial fibrillation not caused by a heart valve problem.1

As a permanent implant, WATCHMAN doesn’t come with the same bleeding risks associated with the long-term use of warfarin.2 This makes it an important option for people with a history or risk of serious bleeding on blood thinners. Newer blood thinners (also known as novel oral anticoagulant drugs) offer additional options to warfarin, but they don’t take away the long-term risk of bleeding.1

If You Have Serious Bleeding Concerns

If you have atrial fibrillation and you take a blood thinner to reduce your stroke risk, you’re probably aware of the bleeding risks that come with your medication. Maybe you’ve even experienced a serious bleed and had to go the hospital. 

Hear about two real patients who had serious bleeding events while taking blood thinners. In the following videos, Marjorie and Billy talk about their experiences, the effects on their families, and why their cardiologists recommended WATCHMAN. If you, too, have a history of serious bleeding, then WATCHMAN may be right for you. 

You may also be a candidate for WATCHMAN if you have a lifestyle or condition that increases your risk for serious bleeding. Certain lifestyles or conditions may increase your bleeding risk by putting you at higher risk for falls or making you prone to injury in other ways. Talk to your cardiologist about your risk.


Richard developed a hematoma in his abdomen, which then caused a crushing of the femoral nerve and a damage to the leg that restricted him completely on mobility in 2010. The hematoma was developed through long-term anti-coagulant use, so it was strongly recommended to him to cease any anti-coagulant. Richard discussed his options with his cardiologist who recommended a left atrial appendage closure therapy.

Judith was diagnosed with atrial fibrillation and while waiting for ablation, she had a small stroke. She was put on warfarin, but had another small stroke so they took her off warfarin, but she had a major stroke that paralysed down her left side. Judith discussed left atrial appendage closure therapy option with her doctor. See her story.

The WATCHMAN Implant may be right for people who meet the following criteria:

  • They have atrial fi­brillation not caused by a heart valve problem (also known as non-valvular AF)
  • They are at high risk of bleeding or they have experienced bleeding
  • They have contraindication or intolerance to oral anticoagulants

As with any medical procedure, there are risks involved with WATCHMAN. See the Important Safety Information below for a list of possible complications, and ask your cardiologist about the risks and benefits of WATCHMAN.

Who Is WATCHMAN Not For?

People who should not receive the WATCHMAN Implant include but are not limited to those who:

  • Should not or cannot undergo heart catheterization procedures
  • Have a left atrial appendage that is too large or too small to fi­t the WATCHMAN Implant

Ask your cardiologist if any of these conditions apply to you.
